LIME-SPREALING ATTACHMENT FOR MANURE SPREADERS.

Application filed March 26, 1924. Serial No. 701,949. I

This inventionrelates to a manure spreading attachment.

One of the objects of the present invention is to provide a manure spreading attachment which is adapted. to convert the ordinary manure spreader into an efficient lime, sand or pulverized vfertilizer spreader. A further object of the invention is to provide a: simple and easily detachable device which can be readily attached to or detached from the ordinary manure spreadein.

A further object of the invention is to provide a receptacle or pan positioned at the delivery end of the apron of the spreader and beneath the heater for preventing the loss of the material being spread between these parts.

These and other objects are accomplished by providing a construction and arrangement of the various parts in the manner hereinafter described and particularly pointed out in the appended claims.

j Referring to the drawings, Fig. 1 is a cross sectional view of a portion of a manure spreader showing my improved attachment mounted therein. I

Fig. 2 is a perspective view of the detachable pan or receptacle. 7

Fig. 3 is a top plan view .of one of the 30 paddles showing themanner in which it is removably secured to the teeth and bar of the heater, and

Fig.4; is a front elevational view of the paddles shown in Fig. 3,;

36 In carrying out my invention I have provided an improved form of an attachment.

for a'manure spreader which is adaptedjfor use in connection with spreading materials that are inpulverized form. In connection with distributing and spreading materials that are in powdered or pulverized form the ordinary manure spreader is so constructed that the beater which ispositioned to the rear and adjacent the'delivery end of the apron in such a manner that any pulverized material being distributed by the ordinary manure spreader drops down between the heater and the end of the apron and does not give the desired spread over a wide area that is required. I

For the purpose of illustration I have shown a manure spreader comprisinga body 6 10 mounted on the usual supporting axle 11 and carrying wheels 1.2.

are operatively driven.

Secured to the sides of the body 10 and extending upwardly therefrom are extension members 13 which form bearings for the usual rotating retarder 14. Operatively mounted in the bottom of the body or box 10 is the usual endless belt conveyor 15, which is provided with a plurallty of lugs 16 for engaging and carrylng the material in the manure spreader rearwardly toward the delivery. end thereof. The endless conveyor belt 15 is operatively driven by a driving roller 17, which is geared to the carrying or traction wheels 12 in a manner well known. Rotatably mounted in bearings formed in the sides of the body 10 above and to the rear of the delivery end of the endless conveyor belt 15 is the usual beater 1 8. The beater 18 is provided with the usual cross bars 19 which in turn are provided with radially projecting teeth .20. The beater 18 together with the radially projecting teeth 20 are positioned with'respect to the delivery end of the endless'conveyor belt 15 in such a,

manner as to form a relatively small space between the lug 16 of the conveyor belt and the teeth 20 of the beater, to positively insure or prevent either of these members or parts from striking each other in their normal operation. Positioned to the rear of the beater 18 and mounted on arms 21 secured to the body 10 of the manure spreader is the usual wide spread distributor 22. The

'wide spread distributor 22 is so positioned that as the material to be distributedis conveyed by the beater overthe top thereof in the direction indicated by the arrow it is deliveredto the wide spread distributor and spread over a wide area or swath. The wide spreader 22 and beater 18 as well as the rotating retarder 14 is operatively geared to the traction or carrying wheels 12 in the manner well knownand for this reason itis thought unnecessary to specifically describe the manner in which all these parts A novel feature of spreading attachment comprises a detach- I able pan 23 which has its rearward portion my improved lime curved concentrically as shown at- 24 in a manner to conform with the curvature or path defined by the rotating teeth 20 of the beater 18. At a point between the beater 18 and the delivery end of the endle'ss conveyor 15 the pan 2a deflects downwardly as shown at 25 and curves under the driving roller 17 of the endless conveyor 15 as shown at 26 and extends forwardly as shown at 27 to a point adjacent the axle 11. The extension is provided on the opposite-sides thereotwith hooks 28 which are adapted to be detachably supported on the axle 11 for sup porting the pan at its forward end beneath the lower ply of the conveyor beltor apron.

The pan 23 is preferably made of a single piece of sheet metal and is provided with opp site y disposed sides 2 adja n h Cu ed p rt 2 s a to m substa tia ly a receptacle for receiving any loose material hat b dropp d b t e apr n or tqnreyerhelt a d th e ttr- The sid s 2. @gtend forwardly nd tape nwardly a 3 ja nt t e ex ns o 2 Th .re rwardven f, the va 2 i Sn 3 OJ-"tQ i tl st' P oximi y to the path fihed by th te th'of the h ater 8 y a k 31 hich in ti -mare adap d t b ecure t t e ide of th ody i Fro thle ab v des ip io t ll h readily een th t as lim or o r pulverize material be ng distri ed i c n ey d rearward y y the ndles hv y 0rr i pr 1.
